Ted Cruz has won the Republican Iowa caucus, a necessary victory that saved him from what would have likely been the beginning of the end of his presidential campaign. It's unclear if Cruz has the coalition of voters—specifically, women voters—to go beyond Iowa, but he had no problem appealing to Republican women in the Hawkeye State. Forty-eight percent of Republican caucusgoers in Iowa were women, and of those more chose Cruz than any other candidate, according to entrance polls. What's more, young conservatives got behind Cruz: More women and men under age 45 selected Cruz than any other Republican candidate. What, exactly, about Cruz appealed to GOP caucusgoers? Entrance polling shows that the highest priority for Iowa Republicans was a candidate who "shares my values." Among those voters, Cruz was the clear winner, topping Donald Trump 38 percent to just 5 percent. Also among caucusgoers, most aligned with Cruz in their attitude toward government. Ninety-one percent said they were either angry or dissatisfied with how the federal government works, and a majority felt Cruz best captured those sentiments. All that said, there's no question Cruz would face a hostile crowd in a general election. Before the "bimbo"-bashing Trump got into

Ted Cruz has won the Republican Iowa caucus, a necessary victory that saved him from what would have likely been the beginning of the end of his presidential campaign. It's unclear if Cruz has the coalition of voters—specifically, women voters—to go beyond Iowa, but he had no problem appealing to Republican women in the Hawkeye State.

Forty-eight percent of Republican caucusgoers in Iowa were women, and of those more chose Cruz than any other candidate, according to entrance polls. What's more, young conservatives got behind Cruz: More women and men under age 45 selected Cruz than any other Republican candidate.

What, exactly, about Cruz appealed to GOP caucusgoers? Entrance polling shows that the highest priority for Iowa Republicans was a candidate who "shares my values." Among those voters, Cruz was the clear winner, topping Donald Trump 38 percent to just 5 percent. Also among caucusgoers, most aligned with Cruz in their attitude toward government. Ninety-one percent said they were either angry or dissatisfied with how the federal government works, and a majority felt Cruz best captured those sentiments.

All that said, there's no question Cruz would face a hostile crowd in a general election. Before the "bimbo"-bashing Trump got into the race, Cruz was the Republican candidate progressives and feminists loathed most for his position on women's issues, as is well-documented by a slew of fire-breathing attacks posted just after he announced last March. Bust noted: "electing Ted Cruz for president would be catastrophic." Think Progress said: "Ted Cruz just laid out the most anti-woman agenda yet." Bustle wrote: "Ted Cruz's positions on women's issues would make him a disastrous president."

What should worry Cruz is that among Republican Iowa caucusgoers who think a candidate who "can win in November" is the highest priority, Marco Rubio creams Cruz, 44 percent to 22 percent. That's a pretty strong indication that Cruz may be seen as principled, but unelectable. If Republican women are pragmatic in 2016, Cruz probably won't go the distance.
